primary location of btrfs-progs changelog: The wiki?

Hi, I'm just wondering where the primary location of the btrfs-progs changelog is located, because I'd like to include upstream changes in the Debian package. Is it really the wiki? If so, it would seem my options are copying+pasting with every release, or writing a script to download the page,

Everyone, thank you very much for helping me to learn more. Getting up to speed takes forever! I posted an idea relating to this thread, but it's more read latency rather than throughput related, but I'm not sure what the right way to link overlapping threads is, so here is how to find it:

Add device while rebalancing

Good morning, I am new to this list and to btrfs in general. I have a quick question: Can I add a new device to the pool while the btrfs filesystem balance command is running on the drive pool? Thanks -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a

[PATCH] btrfs: Switch to generic xattr handlers

The btrfs_{set,remove}xattr inode operations check for a read-only root (btrfs_root_readonly) before calling into generic_{set,remove}xattr. If this check is moved into __btrfs_setxattr, we can get rid of btrfs_{set,remove}xattr. This patch applies to mainline, I would like to keep it together

Hi Omar, Chris, I have reviewed the free-space-tree code. It is a very nice feature. However, I have a basic understanding question. Let's say we are running a delayed ref which inserts a new EXTENT_ITEM into the extent tree, e.g., we are in alloc_reserved_file_extent. At this point we call
